Fix session expiration issue

After testing NXP-28226 with the new authentication method (OAuth2) which should have fixed the "Previewer Server lost authentication against Nuxeo", we've met another issue.

Reproduction:

• Leave a browser tab open on the Web UI annotation tab for 1 hour without any activity.
• After 1 hour, go back to the browser tab and start doing some annotation drawing.
• The Previewer UI sends the annotation to create to the Previewer Server and gets a successful response, but the freshly created annotation disappears, and nothing is saved on Nuxeo side.

Expectation:

We expect to be able to create annotation whereas it wasn't possible in this case.
